hmm are you sure its a plane?
Not just your neighbour with a belt sander
Isn't there a commercial airport nearby, it doesn't necessarily needs to be a military aircraft to make weird noises.
I live 20 km from Schiphol Amsterdam international airport, I hear 747's fly over at 1,800 feet every 5 minutes or so.
They often sound very weird, almost like they are 'shifting gears' (which is of course impossible...) and the sound fades away very quickly, even
when they fly straight over my house...
